Answer:
Mainly, the number of genes that control traits.
Explanation:
Polygenic inheritance does not follow Mendel's law of dominance. According to Mendel the dominant trait will mask the recessive trait however, this is not always the case. Polygenic inheritance states that traits are controlled by two or more genes and is also dependent on the environment.
Let's take skin color for example. A fair-skinned person will have a child with a dark-skinned person.
Mendelian inheritance would assume that the offspring would either be fair or dark only.
Polygenic inheritance would assume that the offspring would be either fair, dark, or a tone in between, depending on the environment they are in as well.
Hope you understood it.
A is the correct answer, I believe. There are not usually enough doners as there are people who need the organs, so doing this COULD help (though it's gross)

Answer:
No
Explanation:
Both A alleles and B alleles are dominant over the O alleles. This means that both parents must have an O allele present to even have a chance of having a child with type O blood. Lets say the mother has type O blood with the father having type AB blood. The possible combination would be: AO, BO, AO, BO. The punnett square should look like this:
A B
O AO BO
O AO BO
Warm ocean currents originate near the equator and move towards the poles or higher latitudes while cold currents originate near the poles or higher latitudes and move towards the tropics or lower latitudes. The current's direction and speed depend on the shoreline and the ocean floor.
